Footing
Pier and beam footing
Footings are anchors of a pier and a beam foundation. Main materials used are
reinforced masonry, supported by reinforced concrete. It is important to ensure that the
footings are fixed below the maximum frost depth.
Pier and beam foundation is made up of concrete footing and the piers main function
is to support the structures and the floor joist. In most cases, these foundation leaves a
ventilation space underneath the floor depending on the slope of the land upon which the
building is built. The piers spacing mainly depends on the arrangement of floor span framing
especially where the load bearing walls and partitions are located. Pier spacing in most cases
have a range of 8 – 10’1.
